Abstract

Recently, the development of information and communication technology, especially computer networks, is now so rapid and has become one of the indicators of human progress. Along with these developments, users' needs for network access quality are increasing, both LAN (Local Area Network) based. The quality in question includes high data transmission speeds, stable connections, and a system that is able to support various activities without interruptions or problems that can reduce work productivity. With the existence of LAN networks, the use of information and communication technology can be an effective connecting medium. This research was carried out with the aim of helping to analyze and simulate the Local Area Network (LAN) network which is equipped with integration using the Cisco Packet Tracer application at the Gelebak Dalam Auxiliary Health Center. The presence of a LAN network will allow various processes and transactions to be carried out more efficiently, reduce potential problems, and improve the quality of services provided by institutions or organizations. This project is for that. This study will assess the condition of the LAN network at the Gelebak Dalam Auxiliary Health Center using Cisco Packet Tracer. It is anticipated that the LAN network in the health center can be optimized to be more efficient.

Abstract

The exiled figure LaTahazan Florisr is a business located in Palal, the city of Palembang. This business is a business that is engaged in ordering flower bouquets, bouquets, flower boards, standing flowers and others. The manual sales system has many drawbacks which are mostly errors in record-keeping, and difficult data search because every time you search for the seller data you have to search in the ledger. To solve these problems, a web-based cashier system is needed. This study adopts an observation method, a literature study using the waterfall method in designing a web-based cashier information system. The system is built and designed to help store admins or cashiers in making sales reports and purchasing calculations easier. The results of this software design are expected to help the work process to be more efficient and can reduce the possibility of calculation errors, and speed up the creation of reports. The designed system describes how each component of the system will work optimally, from managing transaction data to creating ready-to-present sales reports.

Abstract

This study focuses on analyzing the quality of service (QoS) and measuring the quality of the internet network on the Starlink network In Karya Jaya Village, this study uses the QoS parameter measurement method. The parameters used include delay, jitter, packet loss, and throughput. This measurement is done using the Wireshark application to monitor and capture the traffic of data packets in the network. This application provides detailed information about network performance and can identify potential problems in the data transmission process. The throughput measurement results showed that the throughput was higher during sunny weather, with a value of 74k, compared to the rainy weather time which only reached 158k. Despite the difference in throughput values, the two values still showed "Excellent" performance. Throughput is one of the main indicators that shows efficient network performance. These findings offer a unique contribution by providing real-world case-based analysis relevant to the needs of modern networks.

Abstract

Technological developments in the field of information systems have brought significant changes in the way we conduct transactions, communicate, and access services. One of the aspects that is focused on in the development of a website-based information system is the design of the user interface (UI) and user experience (UX). With technological advancements and wider adoption, intuitive, accessible, and user-friendly UI/UX design has become essential to ensure that information systems can meet users' needs efficiently and effectively. This study aims to evaluate user experience focusing on the ease of use and effectiveness of the user interface (UI) on the SkylarTopup information system. This process involves identifying challenges faced by users in interacting with the website, such as difficulties in navigation, slow response times, and design aspects that can be improved. Through SUS-based analysis, it is hoped that recommendations can be generated to improve the quality of UI/UX, so that SkylarTopup's information system can be more optimal, efficient, and better meet user needs. The results of the SUS score obtained show that although this system can be used quite well, there is potential for a significant improvement in terms of usability.

Abstract

The role of public media such as websites is needed to disseminate products or goods, especially for small businesses that have the potential to face competition with other businesses. Websites are an alternative solution to the limitations of the business area and provide the speed of bidding and provide the opportunity to become the best seller. E-Commerce makes consumers more time-saving, and differentiates cheaper prices, it provides various things to sell and minimizes crowding in stores, E-Commerce Websites support our trade business by providing products and services online to users in various regions. Websites are an alternative solution to the limitations of the business area and provide the speed of bidding and provide the opportunity to become the best seller. The researcher found a problem that the border computer partner figure in data processing is still done manually with paper media. Therefore, the author took the initiative to design an E-Commerce information system for Computer Embroidery Partners in Palembang City with a waterfall method design. This waterfall method has a fairly clear workflow, measurable work time and clear documentation. This research was tested with the Blackbox test, with this website it is hoped that it can facilitate the sales system for Computer Embroidery Partners in making sales reports automatically and with this website it is hoped that it can be a promotional medium for Computer Embroidery Partners
